Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.

Industrial grade and "E" suffix devices shall be tested to subgroups 1 and 4 unless otherwise specified.

Military grade devices ("H" suffix) shall be 100% tested to subgroups 1, 2, 3 and 4.

Subgroups 5 and 6 testing available upon request.

Device has internal shutdown feature that pulses the output with a low duty cycle during faults.

Refer to DSCC SMD for electrical specifications for devices purchased as such.
